The cooks compete in the first Service Challenge of the season. Two teams, aided by mentors Matt Sinclair and Sashi Cheliah, must cook an entrée and a main course dish for 30 diners.

The top 24 try to stand the heat in the kitchen, with 90 minutes and an open pantry to cook their dishes and impress the judges, focusing on hospitality.

This season, contestants compete in teams in the ultimate David vs Goliath battle. In the first challenge, they must cook a dish which recognises their strengths.

The first elimination of the competition sees contestants in a two round challenge, where the maker of the best jaffle in round one is safe, but the maker of the least impressive dish that changed their life in round two will be sent home.

Twenty-six mystery boxes contain single ingredients that correspond with the letter on the box - chefs must cook using their designated ingredient, with the bottom four in danger.

Today's guest chef is Adriano Zumbo and his Polly Wanna Waffle is more difficult than any other dish he has presented in the kitchen.
